摘要

我们考虑了一个由单无限分量矢量自旋和单模谐振子组成的开放Dicke模型，假设它们之间存在jines - cummings型相互作用。基于超算子形式论研究了其代数结构和动力学。证明了通过显式可逆超算子将其刘维量转化为分别由修饰自旋和修饰谐振子产生的两个独立的刘维量之和。

On the Open Dicke-Type Model Generated by an Infinite-Component Vector Spin

We consider an open Dicke model made of a single infinite-component vector spin and a single-mode harmonic oscillator assuming a Jaynes-Cummings type interaction between them. We study its algebraic structure and dynamics based on superoperator formalism. It is shown that by an explicit invertible superoperator its Liouvillian is transformed into a sum of two independent Liouvillians that are generated by a dressed spin and a dressed harmonic oscillator, respectively.

期刊介绍： The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication, filtering, memory and cooperative behaviour, etc., in open complex systems.
